WARNING: Do not apply directly to pool. Use one of the following dosing methods: Maintain pH level within the ideal range of 7.2 – 7.6. If not in this range, adjust. Skimmer: Place one tablet in the skimmer basket per 45,450 litres (10,000 gallons) of pool water and adjust tablet numbers as necessary to take account of your water flow to achieve 1–3 mg/l (ppm) chlorine level. Floating Dispenser: Fill the floating dispenser with tablets and adjust the aperture mechanism at the bottom of the dispenser to obtain the 1–3 mg/l (ppm) desired range. Alternatively keep the dispenser aperture constant and vary the tablets inside to achieve 1–3 mg/l (ppm) chlorine level. The dispenser should be removed from the pool while swimmers are bathing. NOTE: As this product releases chlorine relatively slowly it may be necessary to shock dose (oxidise) your swimming pool water prior to their use to first establish a chlorine level more rapidly.
Recommendation: It is recommended that you periodically (e.g. weekly/fortnightly) shock (oxidise) your pool water. ALWAYS ADD CHEMICALS TO WATER & NOT WATER TO CHEMICALS. NEVER MIX CHEMICALS.
